The Dragon Fist (Ryū-Ken 竜拳; ; ; ) also known as Dragon Fist Explosion (Ryū-Ken Bakuhatsu 竜拳爆発; ; ; ) or Super Dragon Fist is the only attack Goku comes up with himself. He begins the attack by making a straight fist faced at his enemy, then once his fist, along with his own body, exits the stomach or chest of the target, the energy will explode out into the form of a giant golden dragon which bears resemblance to Shenron and then finally collide into the target, possible destroying it in it's path or leaving a gaping hole, hence the name Dragon Fist. Widely considered by fans as the second strongest attack Goku has. He has used it on Hirudegarn, Super 17, Eis Shenron, and Syn Shenron. However, it only directly killed Hirudegarn and Eis Shenron, although it allowed Goku to win against Super 17 using a Kamehameha to vaporize the evil Android afterwards.
Though it is never stated explicitly that Goku originated this move (but he is also never seen learning from anyone), the move's origins appear to hail from the first Dragon Ball anime. The execution of the move is virtually identical to the move he used to kill King Piccolo (called Penetrate! in Tenkaichi 3), minus the initial Kamehameha and instead of a golden dragon, a silhouette of a Great Ape appears as Goku's inner powers.
Trivia
- This is the one of the few rush attacks in the Budokai Tenkaichi video game series capable of being executed against giant characters, such as Great Apes and Slug (in his Giant form) since Goku uses it against Hirudegarn.
